I'm hoping for any clear results that any tester/number-cruncher might have documented about whether non-strength modifiers (like dex-to-damage or int-to-damage) benefit from Power Attack, especially the extra damage gained through combination of PA and a two-handed weapon.
I may have gotten lazy or defeatist in my search of the forums; in any case I could not find this info so far.
Please assist/advise, thanks much!
